Jim, I will check on the answer with my friend. My guess is no, but I'm not
sure.

Alan, how large is the foundation for one of these towers? Does the
engineer from Japan have to supervise the installation of the base? Jim

The width of the bottom section is 65 inches, less than I would have
guessed. Width of the top section is 18 inches. I don't know what the foot
print of the rotating base is, but that may well be significantly larger
than the first section of the tower itself.
Here is an interesting fact, when buying any of these towers, you must pay
for a Luso construction engineer to travel to your station from Japan, to
supervise the entire preparation and installation activities.. You must pay
all of his expenses, including airline tickets, hotel room, etc. The reason
for this is to assure that the tower is installed correctly. My friend that
just bought the 90 foot model, had to pay around $5 grand for the engineers
presence.

heavy duty alright at around 15 tonnes...that sounds a bit on the heavy
side? A heavy duty 68 foot del hi only weighs maybe 500 pounds total...this
must be a very very large tower? that is, very large spread at the bottom to
support so much weight at the top?
Obviously a 68 foot del hi is only rated for about 12 square feet of wind
load though lol.
I can't imagine shipping on a beast like that haha.
